父母离异， 小孩随父在美生活，母亲来探访， 持有10年签证，第一次在机场被拒入境， 原因是签证时说是两人来，实际来时只来一人。 5年以后， 又一次计划来访（非移民）， 在来之前需要做哪些法律手续？-You may not need to do it.
1）I-192 表
-I don't think you need to provide this form because it seems your denial of entry was not due to the crimial history or any violation of US immigration law. If the denial was just because the CBP officer considered the purpose of your travel was not consistent with the visa type which you used to enter US ( (e.g. the officer suspected you might stay in US permanently after you used B-2 visa to enter US), then you may just use a new B-2 visa to enter US. I am not sure whether the old visa stamp is still valid after you were rfefued to enter US even if it does not expire yet, so you had better apply for a new B-2 visa to enter US.
You may consult an immigrant lawyer because we do not know the details why you were refued to enter US at that time..
2）还有什么？
